| dc.description.abstract | Chromatographic separation of the methanolic leaf extract showed the presence of a common spot in all the 10 species of Piper and hence appears to be a chemotaxonomic marker for the genus. Besides this generic marker, species specific spots were found in P. nigrum, P. betle and P. zeylanicum. Further the phenolic spot designated No. 5 was found in all the diploids and No. 2 in the tetraploid species of the genus. The leaf epidermal characteristics of Piper species showed that a combination of two or more characters could be used to identify species such as P. nigrum, P. longum, P. betle, P. chuvya and P. trineuron. A high positive correlation was observed between chromosome number (ploidy level) and guard cell length, but the correlation was negative between chromosome number and stomatal index values. | en_US |
